adapted to fit closely and exclude the air.

tlntedtate A. G. GOOI), OF READING, PENNSYLVANIA.

Letters `Patent No. 91,432, dated .Tune 15, 1869.

To all 'whom' 'it may concern Be it known that I, A. G. GOOD, ofReading, in the county of Berks,- and State of Pennsylvania, have in:vented a, new and valuable Improvement in Devices `for Raising andKneading Bread; and I do hereby declare that the following isY a full,clear, and exact dei scription of the construction and operation of thesame,

reference being hadto the annexed drawings, making i `a part ofthisspecitication, and tothe lett-ers Vandfig :lures of reference markedthereon.,

'Figure 1, of the drawings, is a'representaton ,of a

Vlongitudinal section of my machine.

Figure 2 is a vertical `sectional view of the same.

Myinvention relates to means for manufacturing bread; and Y Itreonsistsi-n the construction and novel arrangement of devices for kneading flourinto dough, and

aiding in the process of raising the same, preparatory to baking. Tothis end, I construct a box, `with a suitable lid,

`interior of this box with zinc. as shown on the drawl ings, leaving aspace at the bottom, for purposes'hereinai'ter mentioned.

The zinc, lining is represented onthe drawings by the yletter A. Othermaterials, such as tin, or iron, may be used.;

l but, for many purposes, zinc is preferable.

- The lower part `of this lining is made concave, as

shown. i

lIhedetter C represents a shaft, operated by a crank,

. as shown, and to which is attached a series of beaters,

` i marked I), arranged on said shaft in a diagonal position, asrepresented.

This shaft works in bearings in the ends of th'e box, and ismaderemovable by means vof a wedge, E, fitted I line the Y in a suitableslot in one end of the box, above the shaft, and extending from the topof the box to said shaft.

When the shaft isremoved from the box, I iill the openings, left therebyin the ends of said box, by means of the stOpperS, marked G. By the useof these stoppers, air may be admitted or excluded from the box v atwill.

Beneath the lining A, I place' a pan, marked H, to contain Warm water,which I use, when desirable,to aid in theprocess called raising thedough.

The door is mixed and kneaded in the box by means ofthe revolvingbeaters, and then the shaft is removed,

and the openings closed by means ofthe Stoppers. The pan H is then lledwith warm or hot water, and the dough lei't to raise. The result is arapid distri- 'butiou of' carbonic-acid gas from the leaven throughoutthe dough, and the same is made ready for the oven in a very'brief spaceof time.

'lo hold the wedge E in place,Iax hooks, marked d, to the ends of thebox, which fit in suitable openings in the bottom of said wedges.

That I claim as my invention, and desire to secure by Letters Patent, is

A bread-kneading and raising apparatus, .having lining A, shaft O withits beaters, wedge E, Stoppers G, and pan H, constructed, arranged, andoperating substantially as specified.

In testimony that I claim the above, I have hereunto subscribed my name,in the presence of two wit- DGSSGS.
